Mouse Graphic error

[krillinballz]

When i install retail mac and update to 10.6.6 use multibest for audio and graphics and bootloader. When i restart and change my res to 1024x768 my mouse turns blue i tryed every thing to fix it. Only thing that make's it normal is when i resize the mouse pointer to a stupidly large size. Hopfuly some one can help me figure this out i had to re install mac and windows after i changed my ram out could not get them to boot thus the problems with my mac started. Thank you in advance
